right now it has a cam, longtube headers, and flowmaster muffler.... I want to make it quieter since cops will bug me alot... what are some quiet exhaust brands? I'm looking to buying a hi flow cat since it doesnt have one and also maybe the stock exhaust??? would i have to change the Longtube headers also in order to make it quieter?
Quieter exhaust for ls2 pontiac GTO?
